Treatment of high concentrated organic wastewater

One case: Paracetamol production of refined liquor resource recycling

Jiangsu, a pharmaceutical factory production of acetaminophen products containing acetaminophen on mother liquor wastewater, about 1.7% have peculiar smell, every day about 60 tons of raw water CODcr near 20000mg/L. The original method is three effect evaporation of recycling materials, after process improvement with functional polymer materials instead of three effect evaporation, eluent production function material apply, functional materials can be used repeatedly after desorption. So that the cost of each ton of paracetamol products to reduce the cost of 500 yuan, played a waste water treatment, energy saving, consumption, reduce costs, such as the role of the four, the company was therefore the local economic and Trade Commission of the $100 thousand reward.
